UNWINDING DEVICE.

Specification of Letters Patent.

Application filed October 1, 1919. Serial No. 327,720.

To all whom it may concern:

Be it known that I, JENNY ZERVUDACHI, ae RODOCANACHI, asubject of the King of Greece, and residing in Paris, France, 51 Avenue Victor Hugo, have invented certain new and useful Improvements in and Relating to Unwinding Devices, of which the following is a complete specification.

This invention has for its object a reel or skein unwinder which can be easily taken to pieces and is constructed of several parts which occupy little space, so as to be kept in a work table or work bag and when put together allow of the reeling off in proportion to the progress of the work of any spun textile material, such as wool for example, which is wound in a skein, without the latter constantly rolling on to the ground and thus running the risk of becoming soiled or trodden under foot and detached from the work by breakage of the thread.

This unwinder is composed of four parts to wit: a foot terminated at one end by a central pin which may be provided with a screw thread, or be smooth orslightly conical and pierced from end to end along its axis by a cylindrical hole, a base traversed by an axial cavity of the same form as the pin of the foot which may be screwed into it or pushed intoit by-pressure, and closed at one end by a metal plate, a stem adapted to enter freely by one end into the hole in the foot and to rotate therein on a pivot with a blunt conical point carried by the said plate, the other end being provided near its end with an enlargement pierced with a transverse cylindrical hole and a cylindrical spindle which enters this latter with slight friction, the stem and the spindle forming, after being put together, a cross bar intended to support the skein in the manner to be hereinafter described.

In the accompanying drawing which represents by way of example, a constructional form having two modifications, of the subject matter of the invention:

Figures 1 and 2 are elevations of the foot and the base respectively.

Figs. 3 and 4 are elevations of the stem seen in two planes at right angles to each other.

Fig. 5 is an elevation of the spindle. Fig. 6 is an axial longitudinal section of the unwinder incompletely put together, the spindle not being yet put in place.

second, have given to them preferably amore or less ornamental profile (see Figs. 1 and 2) the sole conditions to be fulfilled from a purely mechanical point of view being that the foot 1 shall be perforated, along its axis, by a cylindrical'hole 3, and provided with a member or device which allows of its being attached to the base 2 which device may consist for example of a pin at which may be screw threaded (see Fig. l) and screwed into the axial screw threaded cavity 5 (see Fig. 2) or may be smooth and slightly conical (see Fig. 7) and forced by pressure into a cavity 5 of the same form. In both cases this cavity is closed at its lower end by a metal plate 6 fixed to the base by screws 7 or otherwise.

The stem 8 (see Figs. 3, l, and 6) com.- prises a cylindrical rod, the lower end of which is terminated by a blunt pointed cylindro-conical metal pivot 9 and the upper end by a rounded ogival tip 10, below which is made an enlargement 11 pierced with a transverse hole 12. Instead of the pivot intended to support the stem 8 being on the stem a pivot 9 may, as is shown in Fig.

7, be rivetedto the plate 6, in which case.

the stem is terminated at the bottom by a metal socket 13 with a fiat lower face resting on the point of thepivot.

The spindle 14: (Figs. 5 and 7) is a simple cylindrical small rod which enters with slight friction into the hole 12 in the stem 8 sand is terminated by two rounded ogival en s.

To use the unwinder, the foot 1 is first attached in one or other of the ways above described,to the base 2, and the stem 8 without its spindle (see Fig. 6) is then introduced into the hole 3 in the former. The skein 15 of wool for example, to be unwound (represented in dot and dash lines in Figs. 6 and 7) is generally the shape approximately of an ellipsoid of revolution externally, the major geometrical axis 16 of which is surrounded by practically empty space 17. By means of the stem 8 this skein is transfixed nearly along one of its minor axis 18 and is pushed in until by looking through one end of the empty space 17 the hole 12 can be seen. It then only remains to pass in up to about the half of its length, the spindle M which thus serves as a support for the skein and a cross bar to rotate the stem. The work may thus be commenced or continued in proportion to the progress of which the thread 19 already unwound suffers a slight pull which is sulficient to cause the stem to rotate upon itself with an intermittent motion and unwind'the skein without its having to be touched. The removal of the skein and the taking to pieces of the. apparatus are effected by reversing the above described operations.

Each of the parts of this unwinder (the dimensions of which, variable at pleasure, are determined according to the size of the skeins to be unwound) may be constructed in any suitable manner best adapted to the purpose for which it is intended and of the degree of elegance which it may bedesired to impart to it. Thus for example the foot and the base might be made of wood turned or carved or of repouss or carved metal and .the stem and the spindle of hard wood, such as box, citron wood, acacia, hickory or of any one of the substances such as bone, ivory, shell, celluloid or various plastic materials serving for the manufacture of knitting needles, crochet hooks and similar instruments, or even for the purpose of securing lightness of a tube of aluminium or other metal of low density and nonoxidizable or covered with a nonoxidizable coating such as gold or platinum or' one the "oxidation of which does not cause any risk of the skein to be unwound being soiled, as rust would for example, these details of construction being otherwise of secondary importance compared with the essential mechanical principle of the inventlon.

The applicant also reserves the right to construct the foot and the base in a single piece or in twofixed together and inseparable although this structure would be .less advantageous fromthe: point of view of the transport of the apparatus.

What I claim is:

1. An unwinding device, comprising a tubular support, a vertical stem mounted to turn in the support and a removable transversely extending member carried by the stem adjacent its upper end.

2. An unwinding device, comprising a tubular support, a stem mounted to turn in in the foot and provided with a transverse opening adjacent its upper end, and a rod removablyv mounted. in the opening of the stem. 1

5. An unwinding device, comprising a base having a socket in its upper face, a tubular foot having a reduced lower end secured in the socket, a stem fitting'loosely' in the foot, and having an opening adjacent its upper end, a pm bearing for the lower end of-the stem, and a removable and transversely extending member mounted in the opening of the stem.

6. An unwinding device, comprising a base having a threaded opening, a closure for the lower endof the opening, a tubular foot having a reduced and threaded end screwlng into the opening of the base, a stem fitting loosely in the foot and having a pin at its lower end resting on the closure of the opening of the base, and a transversely extending member removably mounted on thestem.

- In testimony whereof I have hereunto set.
